Add dxtbx

[ndevenish]

Draft PR to test build since it doesn't seem to be working locally. An official (tagged) source will be used when ready to come out of draft.

• Title of this PR is meaningful: e.g. "Adding my_nifty_package", not "updated meta.yaml".
• License file is packaged (see here for an example).
• Source is from official source.
• Package does not vendor other packages. (If a package uses the source of another package, they should be separate packages or the licenses of all packages need to be packaged).
• If static libraries are linked in, the license of the static library is packaged.
• Build number is 0.
• A tarball (url) rather than a repo (e.g. git_url) is used in your recipe (see here for more details).
• GitHub users listed in the maintainer section have posted a comment confirming they are willing to be listed there.
• When in trouble, please check our knowledge base documentation before pinging a team.

Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipes/dxtbx) and found some lint.

Here's what I've got...

For recipes/dxtbx:

• requirements: host: cctbx-base>=2021.8 must contain a space between the name and the pin, i.e. cctbx-base >=2021.8
• requirements: host: numpy<1.21 must contain a space between the name and the pin, i.e. numpy <1.21
• requirements: run: python-dateutil>=2.7.0 must contain a space between the name and the pin, i.e. python-dateutil >=2.7.0
• If python is a host requirement, it should be a run requirement.

Here's what I've got...

For recipes/dxtbx:

• There are too few lines. There should be one empty line at the end of the file.
